Incorporating Environmental Flows Into Water Stress Indicator 6 4 2

These guidelines assist countries in assessing water stress, by providing data on environmental flows (EF), which are necessary for the calculation of SDG 6.4.2 (indicator on water stress), with the aim of fostering a more sustainable water supply.

Environmental Water Requirements in Mountainous Areas presents comprehensive and scientifically sound approaches and methodologies for estimating the environmental water requirements and tradeoffs for water allocation by analyzing anthropogenic and natural water needs. The book covers environmental water management issues in mountainous areas, specifically focusing on the Mediterranean region which exhibits significant contrasts in its demographic and hydrologic features. The authors include paradigms and information that will be useful for water resources managers, decision makers, scientists working in the fields of ecology and water resources management, engineers that design hydraulic works, and environmental policymakers. Offers a complete background screening on theoretical and practical guidelines on estimating environmental water requirements in mountainous areas Promotes and guides interdisciplinary work with information on policies and best practices in the field of ecological flows and water resources management Provides examples and case studies on the successful implementation efforts of ecological flows to analyze lessons learned and overcome practical issues and solutions

The ecosystem approach to inland fisheries management (EAIFM) requires the consideration of inland fisheries beyond the confines of the fisheries sector. Inland fisheries can be invisible in some fora and processes that can have major positive or negative impacts upon them. An ecosystem approach implies that inland fisheries should be considered beyond their subsector boundaries. Activities in other domains, such as land and water use, have major impacts on inland fisheries through, for example, habitat degradation and loss. Mainstreaming the values and needs of inland fisheries into these areas is required if their sustainability is to be achieved. The extent to which inland fisheries are included in, or are relevant to, the most directly relevant international conventions, processes and fora, is assessed. These are prioritized based on a combination of the relevance of their mandates, or work areas, and assessed priorities or opportunities for action.

The review presents the strong business case for inland food fisheries in developing countries to be either a co-benefit, or very often the main benefit, of ecosystem restoration. In view of the current state of inland water aquatic habitats the potential for restoration is high. Realizing this potential requires concerted action to overcome current challenges, foremost of which is the invisibility of inland fisheries in many policy arenas as well as technical and scientific fora. The drivers of ecosystem degradation, ecosystem services valuation frameworks and the main technical tools for implementing interventions are presented. Experiences in developed countries dominate the literature but are not necessarily applicable to developing country inland food fisheries. Local communities that have high dependency on inland fisheries and live in close association with inland water fisheries habitats not only provide much higher fisheries values but a management asset that is unavailable in developed countries and the mainstay of many successful restoration programmes. Ten case studies, representing effective restoration of food fisheries from local to basin scale are used to illustrate what can be achieved. The prospects of inland fisheries benefiting from, or contributing to, the UN Decade on Ecosystem Restoration (2021–2030) are good but upscaling the existing progress will require increased and sustained efforts to mainstream the values of inland fisheries including their co-benefits for biodiversity conservation.

Spatial Modeling of Environmental Pollution and Ecological Risk provides valuable information and insights for researchers, students and professionals in geography, hydrology, sedimentology, soil science, agriculture, engineering and GIS as they face increasingly complex challenges around development strategies for a sustainable society. Written by the world’s leading researchers in their field, each article will begin with a short introductory essay that includes an overview of the sections' papers. Individual chapters focus on the core themes of research and knowledge and some topics that have received lesser attention. Each chapter will review the current understanding of knowledge regarding the present study and scope and consider where future efforts should be directed. Discusses issues at the forefront of present research in environmental science, bioscience, ecology, pedogeomorphology, landscape, geoscience, forestry, hydrology and GIS Explores state-of-art techniques based on methodological and modeling in modern Deep learning and Machine learning geospatial techniques through case studies Describes novel control strategies, remediation and eco-restoration, and conservation techniques for sustainable development
